Hard to say when or how often. Bucks have been reported hitting them at all different times, there's no key pattern to scrape activities, in some areas they may hit them on a daily basis in other areas it may be every 2 or enev every 3 days, it's really anybogys guss as to when.
I think a lot of it is based on Doe activity and the phase of the rut, the best advice is to keep an eye on them from a distance and with a little luck they will check them during your watch.
Good Luck
